1 Claim. 1

This invention relates to a cleanser dispenser for use in connection with the flush tank for a toilet and this application is a continuationin-part of our application, Serial No. 128,132, led November 18, 1949, since abandoned.

The present invention has for an object to provide a dispensing device including a container, the walls of which, when the device is in use, are imperforate except for a restricting discharge opening in the bottom part thereof and which container is adapted to carry a liquid detergent for delivery to the water in a flush tank for maintaining the toilet bowl highly sanitary.

It is also an object of the invention to provide a device of this kind including a container for a liquid detergent and having a discharge delivering to the water within the tank and wherein the liquid within the container is normally held against discharge by a partial vacuum within the container and wherein air is forced within the container upon the rise of the water in the tank and a predetermined amount of liquid is discharged from the container into the tank upon dropping of the water level within the tank and before the subsequent rise of the water in the tank is completed.

An additional object of the invention is to provide a dispenser of this kind including a container for a liquid detergent adapted to be positioned to discharge within the iiush tank for a toilet and wherein a discharge of a predetermined quantity of the liquid within the container is effected automatically and without the use of valves or other mechanical parts.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved cleanser dispenser whereby certain advantages are attained, as will be hereinafter more fully set forth.

In order that our invention may be better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a transverse sectional view taken through a iiush tank and an applied dispenser embodying the invention with parts in elevation,

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1, looking in the direction of the arrows,

Figure 3 is an enlarged fragmentary view of the dispenser as comprised in Figure 1, looking upward from below, and

Figure 4 is an enlarged sectional View taken through the closure or the cap for the container and the associated depending cuplike member as shown in Figure 1.

As illustrated in the accompanying drawings, T denotes a flush tank such as employed with a conventional type of ush system for toilets wherein the tank T is automatically refilled to a desired water level after each flushing operation. A detail description and illustration of the system is not believed necessary.

The dispenser as herein embodied comprises a container B of desired capacity. The walls of the container B are imperforate and impervious to moisture except for a centrally arranged lling and discharge opening l in an end wall 2 of the container B. The opening l is defined by an outwardly disposed neck 3 which is threadedly or otherwise detachably engaged by a cap or closure member C.

Snugly fitting Within the cap or closure member C and in close contact with the inner face of the head 3' of the closure member or cap C is a washer Il which has close sealing contact with the outer or free edge of the neck 3 of the container A when the cap or closure member C is properly applied.

Disposed axially through the head 3 and the washer 4 of the cap or closure member C is a tubular pin 5 having at one extremity a surrounding head 6 having close contact with the washer 4. The opposite end portion of the pin 5 is continued axially through the head or end plate -Ea of an inverted cup like member 'l of a desired cubic capacity. The pin 5 extends beyond the head or end plate 6a a slight distance into the member 'l and said extended portion 8 is expanded in a manner whereby the pin 5 tightly holds the member 'I to the outer face of the head 3' of the cap or closure member C.

The expanded portion 8 has direct contact with a washer 9 tightly held against the outer face of the head or end plate 6a of the member 1. As herein comprised the washer 9 is snugly and substantially housed within an area dened by an annular rib Ill pressed from the head or end plate Ba and disposed inwardly of the member l.

In practice the container B is partly lled with a liquid detergent and/or disinfectant which can be readily accomplished upon removal of the cap C. The charged container B is then suspended within the tank T with the applied cap downwardly disposed and submerged within the water within the tank when the water is at its normal high level. As the charge within the container B drops therein, a partial vacuum is formed within the container B above the charge whereby discharge out of the container B through the bore I I of the pin is prevented. l

The container B may be suspended within the tank T in any manner preferred but as shown in the accompanying drawing a hanger bracket I-I is provided. This bracket H comprises an elongated member I2 of desired dimensions and is provided at one extremity with an inwardly facing hook member I4 to engage over the upper edge portion of a side wall l5 of the tank T. The opposite or lower extremity of the member I2 carries the laterally disposed and oppositely directed spring arms I5 between which the container B is tightly held.

As the water level within the tank T rises from below the member I of the applied container B, a certain amount of air will be trapped in the member 'I and forced up through the bore II of the pin 5 into the container B. Upon leaving the bore II the air will pass up through the liquid within the container B and above such liquid and thereby reduce the partial vacuum above the liquid within the container B and create a pressure against the liquid to effect a discharge through the bore II when the water level within the tank lowers below the member 7 as in a ushing operation and as is illustrated in Figure 2 of the drawings. The discharge of the liquid is in drops the size of which is determined by the minimum diameter of the bore I I. The amount of liquid discharged from the container B is dependent upon the amount of air forced into the container B above the liquid therein and which amount is determined by the capacity of the member l.

The liquid within the container B is preferably of a nature and of a strength after being delivered to the water in the tank T to remove the lm and the like which forms upon the interior of a toilet bowl and thus maintain the bowl in a highly sanitary condition.

From the foregoing description it is thought to be obvious that a cleansing dispenser constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated.

We claim:

A device for automatically and periodically dispensing a predetermined quantity of fluid into a flush tank or the like, said device comprising a receptacle to be received and suspended wholly within said tank and having a downwardly disposed open neck portion, a cap removably secured on said neck portion and having a central aperture in its end wall, an inverted cup-shaped member of fixed predetermined capacity with the end wall thereof engaging the end wall of said cap, an opening in the end wall of said member in axial alignment with the aperture in said cap, an annular rib in the end wall of said member concentric with said opening and projecting inwardly of said member to provide a circular recess, the outer wall of said member being imperforate, a washer disposed in said cap, a second washer seated in said recess, a headed fastening element extending through said first washer, said aperture, said opening and said second washer With the head engaging said first washer and having a ared opposite end engaging said second washer to secure said member in air tight engagement with said cap, a calibrated bore in said element, the rate of flow of fluid from said receptacle eing determined solely by the diameter of said bore and the effective capacity of said member, and means for adjustably supporting said receptacle in said tank whereby said receptacle and member may be raised or lowered with respect to the surface of liquid in saidtank to vary the effective capacity of said member.
